Charlie Nesson vs. Rupert Murdoch

MySpace, the Webâ€™s largest social network, has gradually been imposing limits on the software tools that users can embed in their pages, like music and video players that also deliver advertising or enable transactions.

At stake is the ability of MySpace, which is owned by the News Corporation, to ensure that it alone can commercially capitalize on its 90 million visitors each month.

But to some formerly enthusiastic MySpace users, the new restrictions hamper their abilities to design their pages and promote new projects.

â€œThe reason why I am so bummed out about MySpace now is because recently they have been cutting down our freedom and taking away our rights slowly,â€ wrote Tila Tequila, a singer who is one of MySpaceâ€™s most popular and visible users, in a blog posting over the weekend. â€œMySpace will now only allow you to use â€˜MySpaceâ€™ things.â€
